Hi again, Like cable drums, lots of manufacturers have transformers as loads for low wagons. I looked at the internet for a compact prototype and found this.  I liked the oil reservoir as a feature. As luck would have it, I found some silicon water seals which fit inside an audio connector that look exactly like insulators. The heat fins are from transistor heatsinks I milled flat. The oil level is a piece of copper wire inside the plastic tube. Everything is screwed together. I hope Brown Boveri will forgive me for using their name.      Cheers, Howard.

Hello Howard, I like your transformer (especially the oil reservoir level measure), it reminded me of one I have that has been waiting for a place on the layout these last 20yrs. Unfortunately I am not that handy in primary construction and made mine from a plastic KIBRI kit (another awaits). I had a vague idea I could use them in conjunction with the Sommerfeldt accessory bits for electric supply-to-the-overhead coming from an electrical substation.  Regards, Philip

Hi Philip,
I think I have this item but some of the little bits are missing. Like you ,I have had it for many years.
Howard.

Hi Howard,
Of the five, this one is my favorite.
However they are all pretty special creations for so many reasons I am unable to detail.
I worked for a Brisbane company in the 1980s that sold various industrial instruments.
I think it was ABB-Brown Boveri had a manufacturing plant at Darra for building oil cooled transformers.
So we used to supply certain parts for them.
regards
